Abstract
The utility model belongs to a cylinder head structure of an overhead camshaft engine of a motorcycle, which relates to a split cylinder head structure of an overhead camshaft engine. The split cylinder head structure comprises a cylinder head (1), a camshaft base (15), a camshaft cover (8), a cylinder head side cover (3) and a camshaft end cover (12); the camshaft base (15) is positioned at the upper part of the cylinder head and combined with the cylinder head (1) in a matched way to form a demountable split structure of the camshaft base (15) relative to the cylinder head (1); the camshaft base (15) is connected with the camshaft cover (8) into a whole body to form a demountable split structure of the camshaft cover (8) relative to the camshaft base (15); and the cylinder head side cover (3) is connected with the camshaft cover (8), the camshaft base (15) and the cylinder head (1) into a whole body to form a demountable split structure of the cylinder head side cover (3) relative to the camshaft cover (8), the camshaft base (15) and the cylinder head (1). The structural design of the cylinder head structure can avoid part wasting, and simultaneously facilitate part processing.
Description
Technical field
The utility model belongs to the cylinder head structure of motorcycle overhead camshaft engine, is specifically related to a kind of split cylinder head structure of overhead camshaft engine.
Background technique
At present, the cylinder head modular construction pattern of most of overhead camshaft motorcycle engine, employing be the monolithic construction of cylinder head, camshaft holder, camshaft cover.Because cylinder head partly is made up of firing chamber, inlet and outlet valve, spark plug etc.: the alternate cycles effect that high temperature, high pressure mixing gas are born in the abominable wherein firing chamber of cylinder head operating conditions causes fatigue failure; Inlet and exhaust valve high speed frequent impact valve seat causes cylinder head the wear out failure phenomenon to occur easily.In order to guarantee the motor proper functioning, just need to change whole cylinder head, the part that causes like this not having to lose efficacy is replaced, and causes bigger waste, and simultaneously, the integrated type cylinder head is made, processing difficulties.
Summary of the invention
The utility model purpose is the split cylinder head structure that proposes a kind of overhead camshaft engine, and the waste of part when reducing service engine makes things convenient for the manufacturing processing of part.
Adopt following technological scheme for finishing foregoing invention purpose the utility model:
A kind of split cylinder head structure of overhead camshaft engine mainly comprises cylinder head, camshaft holder, camshaft cover, cylinder head side cover, camshaft end cap; Cylinder head is made up of firing chamber, inlet and outlet valve, spark plug; Tappet, camshaft, duplicate gear and bearing positioning plate are arranged in the camshaft holder; Described camshaft holder is positioned at the top of cylinder head and joins with cylinder head kiss and combines, and, being connected as a single entity by screw accurately behind the location by locating stud on the cylinder head junction plane, constitutes camshaft holder with respect to dismountable minute body structure of cylinder head; Described camshaft holder is equipped with camshaft cover, and camshaft holder and camshaft cover are connected as a single entity by screw, constitutes camshaft cover with respect to dismountable minute body structure of camshaft holder; One side of described camshaft holder has the camshaft end cap, and in order to the fixing sealing of the camshaft that will be positioned at camshaft holder, the camshaft end cap is connected as a single entity by screw and camshaft holder; Described cylinder head side cover is positioned at a side of camshaft cover, bent axle block, cylinder head, and is connected as a single entity by screw and camshaft cover, bent axle block, cylinder head; Constitute the cylinder head side cover with respect to camshaft cover, camshaft holder, dismountable minute body structure of cylinder head.
The split cylinder head structure of a kind of overhead camshaft engine that the utility model proposes, be designed to cylinder head, camshaft holder, camshaft cover part respectively, when like this motor being overhauled, can change the part of inefficacy respectively, avoid the waste of part, the cylinder head of split simultaneously is convenient to the processing of part.
